The only working examples I know about are in Gtk+ code (e.g. in GtkEntry). I didn't study it enough to give a comprehensive explanation (also, the most complex thing I use myself is the composition of accents and letters to accented letters -- but even this would not work with your approach). You can get the basic idea by glancing over gtkentry.c. The text to enter is not obtained from "key-press-event"s at all, instead it is received in input method "commit" callback. But there's more: the surrounding stuff, LTR vs. RTL, knowing when to reset the im context, ... I doubt one can get all this right without actually using it himself. Therefore I would create a new text widget by modification of an existing one (it it's possible legally) instead of writing it from scratch.
